excavating really big pieces from bedrock Monday, November 8 2010
For whatever reason, I have become re-obsessed with excavating the greenhouse well hole, which is quickly becoming a subterranean cistern. I love the straightforward nature of digging, and when working with cracked shale, digging into it has much of the charm of excavating into an enormous ledge of LegoTM. There's also a lottery-playing aspect to it: one never knows how big of a piece one is about to dislodge. I find breaking loose enormous sticks of rock very satisfying but also a little frightening; sometimes a piece is so big that it intrudes into a part of the hole wall I'd assumed I'd be leaving in place. And of course sometimes big pieces are difficult to maneuver out of the hole. One especially large slab I removed this morning was too heavy to lift, indicating it probably weighed more than 200 pounds. I somehow managed to tilt it end over end out the door and into the grass outside, where I left it to lie beside other large pieces for which I will hopefully find suitably-grand uses.
The biggest piece I extracted from the greenhouse well hole today. I wear a size-12 Croc. This piece, like most other large ones, is actually from a layer of bluestone, not shale. The two stone types alternate somewhat in the strata beneath the greenhouse floor.
